Repertorium Homeopathicum Syntheticum.
The structure of the repertory has been simplified, and related information has been brought together by moving the descriptions of pain to the last level. In Synthesis 9.1, several descriptions of pain are now subrubrics of the same modality. Their remedies have been copied to the analogous superrubric, which can be used with or without these additional remedies. In harmony with the restructuring and the streamlining of symptoms, the sorting of symptoms in Synthesis 9.1 has been become more coherent and simplified.
